Determinants of health literacy in early childhood care among marginalized ethnic communities: a cross-sectional study in three border provinces of Thailand.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundEarly childhood development metrics remain substandard among marginalized ethnic minority communities in three border provinces of Thailand. This study evaluated the levels and determinants of health literacy (HL) among primary caregivers to contextualize its role in mitigating adverse child health outcomes.
methodsA community-based, cross-sectional correlational study employing multi-stage cluster random sampling was conducted between July and October 2024. Sample size was determined using an a priori power analysis for multiple linear regression (f² = 0.05, α = 0.05, power = 0.80, 19 predictors), yielding a minimum of 351 participants; 380 caregivers were enrolled. Data were collected using the validated 61-item Parental Health Literacy Scale assessing five HL domains. Multiple linear regression with simultaneous variable entry identified independent determinants of overall HL.
resultsAmong the 380 participants, the largest ethnic group was Thai-Yai (23.95%), followed by Thai-Lue (19.74%), Hmong (19.21%), Akha (17.37%), Lahu (14.47%), Chinese-Yunnan (3.95%), Lee-Soo (1.05%), and Yao (0.26%). Caregivers demonstrated moderate health literacy in the functional, cognitive, critical, and behavioral domains, but exhibited low proficiency in the interactive domain (communicating care needs), resulting in a moderate overall composite score (135.04/199 = 67.9%). Multiple linear regression demonstrated that interpersonal professional support, specifically nurse-led counselling, strongly predicted health literacy proficiency (B = 9.318, p = 0.027). Other significant predictors included receiving information from provincial hospitals (B = 9.013, p = 0.030) and early childhood development centers (B = 7.531, p = 0.032), perceived financial adequacy (B = 3.470, p = 0.013), formal educational attainment (B = 3.064, p = 0.007), and parity (B = 3.252, p = 0.006), identifying primigravida caregivers as a vulnerable demographic.
conclusionsNurse-led counselling, institutional health support from provincial hospitals and early childhood development centers, formal educational attainment, and parity are the primary modifiable determinants of HL in this population. Public health interventions must prioritize face-to-face, culturally congruent caregiver education delivered through dual-tiered institutional networks, with targeted support for first-time mothers.
